Get this from a library. The chemistry of optically active sulfur compounds. [Abraham Nudelman]   This paper constitutes the fourth part 1a,b,c of a continuing series of reviews on the chemistry of optically active sulfur compounds.

In addition to the chiral sulfur compounds described previously, five new classes of optically active sulfur compounds have been prepared: Request PDF | Optically Active Compounds | The article contains sections titled: is of Optically Active Compounds, Determination of Optical Purity, and Assignment of The Chemistry of Organic Sulfur Compounds deals with the chemistry of organic sulfur compounds such as thiocyanates, 1-alkynyl thioethers, thiols, and olefins.

The book is organized into two parts, the first of which deals with the chemistry of chalcogens in relation to other group elements in the periodic The Organic Chemistry of Iron, Volume 1 covers the structures and bonding and the applications of a variety of physical techniques to organo-iron compounds, optically active compounds, as well as chapters on?-bonded,?2-,?3- and?4-organo-iron compounds.

The book discusses the structure and bonding in organic iron compounds; NMR spectroscopy Beside a number of publications, he has edited also a book in the field of enantioselective synthesis.
